CDS Update 4.9.1 will be released on the 5th November 2025. This will deliver live fixes for error messages received in the Customs Declaration Service. 

The following update will apply to UK Import Declarations. 


Country codes – ALL movements 

Upon changes in the CDS release 4.9.0 that required the country code EU to be declared, it was identified that this caused an error message not to be generated when EU was declared within DE 5/15. 


This will be rectified, and an error message will be generated if EU is declared within DE 5/15 


EU as a country code is only permitted to be used to declare the country of preferential origin within DE 5/16; it is not to be declared within DE 5/15 


When the code EU is declared in DE 5/16, within DE 5/15, enter the country code of the EU member state of origin for the goods. 


If Country Code ‘EU’ is entered in DE 5/15, the declaration will be rejected.
